10. bottom plastering mortar paving grid cloth; A cloth two should be adopted to starch or two cloth three slurries at building different parts in strict accordance with designing requirement; When smearing first time finishing mucilage, warming plate answers dry no-sundries, forbid not do first time finishing mucilage, direct paving grid cloth, smear first all over rubber cement, paving grid cloth, smear two times or three times rubber cements interval time must not more than 20 minutes, repave subsides grid cloth after forbidding rubber cement to condense, when improper operation occurring and causing first time rubber cement condensation, condensation rubber cement should be rooted out and again construct; The rubber cement area of warming plate surface smear should slightly larger than the length of grid cloth and wide, and thickness is 2mm, and grid cloth concave surface is pasted wall, launches from cloth mediad surrounding, makes grid cloth embed in finishing mucilage, and grid cloth does not answer fold, empty sticky; Grid cloth periphery lap length transverse direction >=150mm, longitudinal direction >=100mm; When two cloth three are starched, one deck 1.5mm--2mm finishing mucilage between two-grid cloth, must be had not only to separate but also cement both sides grid cloth.The broadwise of grid cloth should be mutually vertical; Fire prevention is corniced, the installation of finished plastic drip strip that awning, window are suitable for reading first should be slotted on warming plate, and paving grid cloth pastes drip strip after completing again, forbids to slot stickup after grid cloth paving is complete again.Preferentially take warming plate to be made 1: 3 domatic method hawk to chew; Building negative and positive angle grid cloth overlap joint adds length and should not be less than 300mm, and highrise building external corner and door and window hole should use galvanized steel wire netting to carry out reinforcement process, and galvanized steel wire netting stretches out 300mm in both sides, angle;

smear top layer plastering mortar; The construction of grid cloth should be continuous, after construction interval is more than 2h, tackles scope of operation benefit and scrape one deck 1.5mm ~ 2mm finishing mucilage when continuing construction; Face rubber cement topping, last cloth two is starched or two cloth three slurries survive.Execute after smearing certain area, with wet hair brush will smear in the same direction spend floating, timely wet curing after topping final set, when temperature on average is higher than 15 DEG C, curing time must not be less than 48 hours, must not be less than 72 hours lower than when 15 DEG C; The destructive operations such as grid cloth must not carry out after having constructed slotting, collide, punching; The moulding of outstanding insulating board for building, should in the complete rear construction of first floor grid cloth paving of warming plate, and after moulding has been pasted, set up one deck grid cloth to strengthen, set up grid cloth lap length and be not less than 300mm, when using GRC decorating outer wall of building lines, must formulate in detail in special construction plan;

field trial, inspection; Unit in charge of construction should formulate Site Test Scheme in special construction plan, should do " model wall ", carry out adhesive strength test and pull-out test to significant points, privileged sites, carries out other and operates targetedly; Entity detection: the inspection of external wall energy-saving structure drill core and the on-the-spot entity detection of external window air tightness.
